- •
Novel indole-3-butyric acid potassium derived carbon was prepared via one-step carbonization.
- •
CO2 adsorption on IBAP-700-0.5 was up to 1.48 mmol/g at 25 °C and 0.15 bar.
- •
Both micropores and N-containing groups were involved in CO2 adsorption.
- •
Contribution of N-containing groups to CO2 sorption on IBAP-500-1.5 was 92.8%.
- •
Pyrrolic-N was responsible for CO2 adsorption on the IBAP-derived carbon.
